What have you done to your Wheel Horse today?

Yeah. Like I said, I'm a little stumped.

 

So it's a hydro, which means no mechanical link between the wheels and the crankshaft. So the engine doesn't necessarily feel the load of that 500 lbs of gravel directly. This also makes a slipping belt less likely to be the culprit.

 

The PTO belt on the other hand is directly on the crank, and the full load of the blades goes on the engine. The deck spindles all feel good and free when turned by hand, but the blades could be sharper.

 

I also hear the engine start spitting when it acts up. I hear the thing miss and crackle at least twice, and it boggs out. But the governor is holding the throttle wide open when this is going on too, so probably not a governor adjustment issue.

 

My two 8 HP units though are gear drive and don't slow when the blades aren't cutting correctly, they push through and smoke the deck belts.

 

Wife found a 312-8 that needs a fuel pump and two tires for $175 tonight. Maybe it just needs a Magnum re-power.

Run it for a few minutes with it bogging and then shut it down and feel around for the heat. It almost has to be in the mule drive or deck bearings unless it's a belt dragging on something. There's gonna be heat somewhere IMO.

Have used heim joints for decades. Have some of various sizes in a drawer. Running low on them so I use them judiciously.

Also have various types and sizes of the rod ends. Quick disconnect and regular.

Have used the quick disconnect many times and not had a problem. They do make it easy to reset toe in, especially if one end of tie rod is not adjustable. 
Plus they were free. Former place of employment scrapped them as overstock since no one was buying replacements. The mechanically minded employees snatched them right up. If they lasted forever on a lift truck , they will do well on a garden tractor.

@CRF857  pto lever dod end , unscrew trundle , go right over original threads with a  3/8 x 24 die nut ?  clean up threading , lubricate , screw a  female heim joint  right on , have this set up and others on 3 horses , refer to this area as a GOLD MINE for  functional improvement  , also a great  spring  pull point  to stop pto cone linkage buzzing ,  years in use , pete

Check the thrust bearing on the end of the PTO.   If those start to seize up it will cause problems as well.

Nope. I had her run it around mowing for a good 10 minutes tonight after dinner. Every bearing in the system was the same temp, and not even warm to the touch. Hottest pulley in the system was the drive pulley on the engine. It sure was chucking grass though.

 

We are almost out of L&G fuel, and I'm not really home tomorrow, so we'll have to wait until Friday to do anymore.

And how does one go about checking those?

 

I am not particularly familiar with this style PTO setup.

Does the PTO look like this?  If so, the bearing on the end that connects to the clutch hoop fails.  Under load it won't spin easily.  If it feels rough, change it.  I'm not familiar with the 1075, so if it has a different PTO I apologize for the confusion.

I'm leaning toward these. Sharp, clean blades would be my first and most frugal thing to rule out though.

It's similar to that style.

If you have photos of those would love to see them.

Another thing to check on the PTO if it's cutting is the C-clip on the out side bearing on the short shaft.  If it comes out of the groove you can't keep it adjusted.

I have replace the c-clips and the short shaft and out side bearing a couple of times on my C-120 in the last 49 years.

@Brockport Bill   went over to threaded rod , heim joint ends , on my  plow , years ago , REPEDITIVE  PROBLEM, SWING QUADRANT ,is also  key , also  use ,a spindle type bolt , no threading, flat washers , make up  perfect  LUBRICATED  SWING START ?  elastic Lok nut  , lets you dial it in . my lever swing squeeze , functions like a rifle bolt , smooth / easy  / solid . check out  my  IMPROVE   PTO LEVER ACTION , site , once I started this GOLD MINE , I just  kept on going ! pete

 

[peter lena 10,013]

@Bill D  those pto bearings are cake , outer sealed bearing  is available at NAPA , inner needle bearing , hangs up  due to engine heat  lubrication failure  , carefully clean out , like carb cleaner  , then , LUCAS  EXTRA HD CREEN CHASSIS GREASE , WHY ? 550 deg flash point , also polyurea rated , anti sling , VERY SPARINGLY , excess slings to  clutch face ,  this is the KEY TO SMOOTH LEVER ENGAGEMENT . my 3 horses have this in use for years , never  burned out a  clutch disc , does any of this make sense to you ?  TRY , ENGAGE , TRY ?  does it work ? is it better ? is it worse ? thats how I ELIMINATE  REPEDITIVE PROBLEMS . ironically , if you  paint  related areas / red / black , they literally disappear .just TRY SOMETHING ! inspire / encourage yourself , that changes how you  look at problems , BTW there is a simple spring  pull on the PTO swing  lever  , down to  related , frame HITCH PIN CLIP ,  STOPS LINKAGE BUZZING !   my  picture  problem  also needs elimination , pete

Killing time to go to the last tractor show so finished up a Onan I got from @Blasterdad at Pullstart's plow day. Should have left the heat shield off 'till after retorque heads run. I have high hopes for this being a decent shelf motor for the 520s. Hope you like the color changes. Just something different.
